Answer Posted / rakesh
star delta connections r used to reduce the numb of
conducors required for pow transmission. Generally we gen
3ph pow, so there vl b 3 coils in generator 2 gen 3ph pow &
each coil vl have 2 point ie. start & end terminals of
coil. so totally 3*2=6 conductors r req to transmit pow
which increases the transmission cost, so in order to
avoid this v use star delta
